Patented Oct. 8, 1929 stares PATENT ori-ics SAMUEL E. SPERBY, OF HOLLIS, NEW YORK, ASSIGNOR T0 INTERTYPE CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK SHIFTING MEANS FOB, MATRIX MAGAZINES' Application filed June 5, 1928. Serial No. 283,057.

The present invention relates to improvements in typographical machines of the general class shown and describedin Letters Patent No. 436,532 granted September 16, 1890 to O. Mergenthaler wherein matrices are delivered from a magazine, by the operation of a keyboard, to a point where they are assembled in aline after which the line is transferred to a point where a type bar or slug is cast therefrom, and it relates more especially to machines of this class which are constructed to contain a plurality ofmatrix magazines for matrices of different fonts, the magazines being shiftable so that one or another thereof may be brought into position to deliver matrices therefrom under the control of the keyboard, as may be required.

Plural magazine machines of this class as heretofore built have usually employed meehanism for moving the lower ends of the magazines through arcuate paths in order to enable the escapements on the lower ends of the magazinesv which control the delivery of the matrices therefrom to pass over orv clear the escapement actuating rods or reeds of the keyboard, but the mechanism required has been complicated and themagazineshifting operations to be performed by the operator have been awkward, difficult vand laborious. In Letters Patent No. 1,229,160 granted to me on J une 5, 1917, is shown and described simplied means whereby the magazines may be shifted to bring one or another thereof into use by moving them in a substantially straight line forwardly or rearwardly, but in order to accomplish this, means are required for lowering the keyboard reeds out of the path of the lower ends of the'magazines, and such a construction presents the disadvantage that it requires the use of a set of short or supplemental reeds above the main reeds and which must-be shifted vout of operative posit-ion between the upper ends of the main reeds and the magazine escapements prior to each shift of the ymagazines and must be returned to such operative position after each shift has been made.

The primary object of the present inven- Y tion is to provide novel and improved magazine mounting and shifting means therefor wherein the construction is simplified and the l magazine shifting operations may be performed with greater speed and facility by the operator while heoccupies his usual seat at the keyboard of the machine, the invention embodying means for tipping upwardly the lower orforward ends of the magazines so that they will clear the upper ends of the escapement actuating reeds, which may be of the usual construction, and means for shifting the magazines either forwardly or rearwardly in a substantially straight line while the magazines are so tipped, thus bringing the desired magazine into position for use, the operating handles or other means for tipping and shifting the magazines being within convenient reach of the operator while he occupies his usual position at the keyboard of the machine.

Another object of the invention is to provide means which is operative automatically by the means which tips the magazines for swinging the channel entrance which serves to direct the returning matrices from the distributor to the magazines out of its normal position between the distributor and the up- .per end of the magazine in use, when the upper ends of the magazines are tipped up- `wardly, thereby removing the channel entrance from a position where it would otherwise obstruct the shifting movements of the magazines and for returning the channel entrance to its normal operative position between the distributor and the upper end of such magazine as has been-brought into use .when the forward ends of the magazines are lowered tobring the escapements on the selected magazine into working'relation with the keyboard reeds on the stationary main frames.` Y

A further object of the invention is to so mount and balance the magazine structure as to enable it to be shifted with minimum eEort, .thus enabling the operator to shift the magazines as may-be desired while seated at the keyboard of the machine.

To these and other ends, the invention consists in certain improvements yand combinations andarrangements of parts all as will be hereinafter more fully described, thel features of novelty being pointed out particularly in the claims at the end of the specification.

In the accompanying drawings Fig. 1 is a front elevation of the upper portion of a typographical machine of the class hereinbefore referred to, the view being partly in section and showing magazine mounting and shifting means embodying the present invention;

Fig. 2 is an elevation of the struc ture shown in Fig. l as viewed from the right hand side thereof, one of th magazines and the cooperating channel entrance being shown in operative position;

Fig. 3 is a view similar to Fig. 2 but showing the upper ends of the magazines tipped upwardly and the channel entrance swung rearwardly to clear the upper ends of the magazines, the full lines showing the maga-v zine unit in its foremost position and the dotted lines representing another position into which the magazine unit may be shifted to bring another magazine into use.

Fig. 4t is a side elevation of the magazine unit shown in the preceding figures but detached from the machine; and

Fig. 5 is a view similar to Fig. 2 but showing different means for mounting the upper portion of the magazine on the main frame of the machine.

Similar parts are designated by the same reference characters in all of the figures.

rlhe present invention is applicable generally to typographical machines wherein a plurality of magazines are superposed to form a stack and the magazines occupy a downwardly and forwardly inclined position on the machine so that the matrices introduced into the upper end of the magazine from the distributor will slide downwardly thereinl by Vgravity and the matrices will discharge from the lower end of the magazine by gravity under control yof escapements usually carried by the lower end of each magazine, the escapements being actuated by reeds or equivalent rods which are mounted in the stationary main frame of the machine and are pushed upwardly under the control of a keyboard so that they actuate the respective escapements on a magazine in operative position. rl`he preferred constructions are shown in the accompanying drawings and will be hereinafter described in detailbut it is to be understood that the invention is not restricted to the precise constructions shown as equivalent constructions may be used and such vwill be included within the scope o-f the claims.

In the present instance, l represents a portion of the main stationary frame of the machine, 2 represents the distributor which as is well known receives the matrices used in Va line from which a cast has been made and returns the matrices to the magazine, 3 represents the channel entrance which may be similar to the channel entrance usually used in machines of this class to guide or direct the matrices dropping from the distributor into the upper ends of the respectivo channels of the magazines and i represents the escapement actuating reeds which are reciprocated vertically in the relatively stationary forward portion la ofthe main frame under the control of a keyboard which may be of the usual well known construction and located at the front of the machine for manipulation by the operator. f

The magazine mounting and shifting means according to the present invention is applicable to two, three or more matrix magazines, three of such magazines designated 5, 6 and 7 being shown in the present instance, and these magazines are preferably mounted in a single unit frame 8 which may be similar to the magazine carrying frame shown in my prior patent above referred to, the magazines being so mounted in the frame that they may be individually removable rtherefrom to enable the magazines to be changed if desired. In the construction shown in Figs. lV to 4 inclusive, the frame '8 has supporting tracks 9 and l0 fined to or formed as parts thereof, and the two upper magazines rest removably on the respective frames 5b and 6b, these frames having lugs 5C and 6C which extend outwardly and downwardly from their edges,

the lugs 5 resting on andbeing secured as for example, by screws, tothe lugs 6, while the lowermost magazine 7 rests removably on the frame unit 8 and the latter has lugs 8C thereon on which the lugs@C rest and to which they are secured as for example by screws.

llt will be understood however that the magazine shifting means embodying the present invention is applicable to other magazine supporting frame structures such for example as one wherein each magazine is mounted on a separate flat frame and the flat frames are secured to the tracks-9 and 10. The magazine as shown are relatively superposed and they are inclined in a forward and downward direction, and the tracks 9 and l0 are preferably parallel to a line connecting the forward lower corners of the magazines, and the tracks 9 and 10 are also preferably inclined downwardly in a rearward direction.y rlllhe lower' ends of the magazines carry escapements 5a, 6a and 7 respectively', the escapements of each magazine, when it occupies its operative position, being` located immediately above and in position to be actuated by the respective reeds 4.

The upper track 9 at each side of the magazine unit rests on a. roller ll which may be composed of a roller or ball bearing of conventional type the outer race of which engages the lower edge of the track, and these rollers or the inner races of the bearings comprising them being supported by short shafts 12 which are fixed in the rear portions of the stationary main frame, the track 9 being thus arranged toy ride in a forward or rearward direction on these rollers, the track 9 being so located with respect to the'center of mass of the magazine unitas to insure a preponderance of weight at the forward end of the magazine stack to tip it downwardly at its yforward end.

A stop 13 which may be formed as a downward extension of therear end of each track 9 Yis adapted to come into engagement with the rear side of the respective roller 11 and thereby limit the forward movement of the .magazine unit, and a stop 14. which may be formed as a downward extension of the forwardA end of each track 9 is Aarranged to come into engagement with the forward face of each roller 11 when the magazine unit has reached the limit of'its rearward shifting movement, the stops 13 and 14 being spaced in conformity with the range of forward and rearward shift of the magazine unit to accommodate the number of magazines used. The forward stops 14C are formed with curved or hooked shaped extensions 14a which are adapted to partially encircle the rollers 11, when the magazine unit reaches its rearmost position, and these forward stops will then serve to support the magazine unit while it is tipped rearwardly about the shafts 12 of the rollers to bring the magazines into rearwardly and downwardly Vinclined position for changing of one or moreof the magazines in the magazine carrying frame. Y

The lower tracks have surfaces 10el arranged to ride on a pair of rollers 15 which may be composed of roller or ball bearings of conventional type located at the respective sides of the magazines adjacent to their lower forward ends. each track having a flange 10" 'projecting downwardly belowy the respective surface 10al and at its inner side to engage the inner side of the respective roller and to thus prevent relative lateralfdisplacement of the tracks from the rollers in either direction. The rollers 15 are so mounted that they will b e in a relatively lowered position when any one of the magazines occupies its operative position and are .movable into a relatively elevated positionto tip the forward ends of the magazines upwardly so that they will clear the keyboard reeds and adjacent parts on the main frame and will be free to shift in a forward or rearward direction.

As shown, the rollers 15 are journalled in crank arms 17 which are fixed to a shaft 18, the latter being'journalled in bearings'19 in the portion 1a of the stationary main frame7 these crank rarms being` fixed to the projecting ends of the shaft at opposite sides of the main frame portion 1a. One of the crank arms has an operating handle fixed to or formed as a part of it, this handle beingl thus fixed to the shaft 18, and said handle which extends downwardly at a side of the portion I 1a of the main frame is adapted to swing in a forward or rearward direction. As shown in F ig.2, when the handle 20 is in its forward position, the crank arms 1 7 will extend substantially rearwardly from the shaft 18 and they will vbe in a relat-ively lowered position, this being the normal position of the handle and rollers when the forward'ends of the magazinesare lowered and one of the magazines is in operative position, and when the handle 20 is swung into the position shown in Fig. 3, the rollers 15 will be slightly beyond a dead center position above the shaft 18 and they are elevated, the tracks 10 resting on the rollers 15 being correspondingly elevated so that the lower ends of the magazines will be tipped upwardly sufliciently high to clear the keyboard reeds l and adjacent parts of the machine when the magazine unit is shifted in a forward or rearward direction. The beyond-dead center position of the rollers 15 above the shaft 18 will enable the rollers 15 to support the weight of the forward end of the `magazine unit, thus rendering it unnecessary for the operator to maintain a hold upon thelhandle 2() to support the lforward ends of the magazines in raised position. The rigid connections of the crank arms 17 to the shaft 18 causes both rollers 15 to swing in unison when the handle 2O is operated, the forward-end of the magazine unit being thus supported evenly at both sides. f-

The rollers 15 controlled by the handle 2O serve to elevate or tip upwardly the forward ends of the magazines so that they will-clear the keyboard reeds preparatory to a forward or rearward shift of the magazine unit, and means is provided by the present invention for automatically swinging the channel entrance 3 into a position to clear the upper ends of the magazines concurrently with the upward tipping of the forward ends of the magazines. As shown, the channel 3 is mounted at its ends on pivots 21 in the'upper portion of the main Aframe at opposite sides of the magazine unit, the pivots 21 being so located that the channel entrance will swing to andfrom a position betweenfthe distributor and the upperend of a magazine occupying the operative position. A bracket 22 supports each end ofthe channel entrance on its respective pivot, and the bracket at one end of the channel -entrance is pivotally connected by the pivot screw 23 to a link 24, the latter being pivotally connected to the handle 20 atthe point 25 which is below the axis of the shaft 18 of the tippingmeans. By this arrangement, a swing `of the handle 20 from the normal position shown in Fig. 2 to the rearward position shown in Fig. 3 will push the link 2-1 rearwardly and the latter acting on the channel entrance will swing the channel entrance from its normal operative position shown in Fig. 2 rearwardly and downwardly to the inoperative position shown in Fig. 3, the channel entrance being then free of the path of the upper endsof the magazines as the latter are shifted forwardly or rearwardly, and when the handle 20 is swung forwardly or returned to the position shown in Fig. 2, the link 24 will pull the channel entrance back into its normal operative position as shown in Fig. 2. y

The channel entrance is thereby automatically swung out of its operative position when the forward ends of the magazines are tipped upwardly and it is automatically returned to operative position when the forward ends of the magazines are lowered. When the channel entrance is swung rearwardly and downwardly to inoperative position, its weight, which is considerable, will act, through the link 24, to hold the rollers l5 in elevated posit-ion, thereby preventing accidental dropping of the forward end of the magazine unit during shifting thereof.

The handle or operating lever 26 is provided for effecting the forward and rearward shifting movements of the magazine unit, this handle being located adjacent to the magazine lifting and lowering handle 2O and approximately coaxiallyr therewith and extending downwardly at a side of the forward portion laN of the main frame so that both of these handles may be reached and manipulated with facility by the operator occupying his usual seat in front of the keyboard. rlfhe handle 2G as shown is fixed to the end of a shaft 27 which is fitted rotatably and in the main frame portion 1a below the shaft 18, the handle 2G being connected to or formed integrally with a lever 28 which extends upwardly from the shaft 27 and is pivotally connected by a rearwardly extending link 29 to the forward end of the upper track 9. A lever 28a is preferably fixed to the opposite end of the shaft 27 and is connected by a link 29et to the upper track at that side of the magazine unit, the levers 28 and 28a swinging in unison and thereby insuringreven forward and rearward shifting motions of the magazine unit, the forward or rearward swing of the handle 26 acting through the levers 28 and 28 and the links 29 and 29 to cause forward or rearward shifting movement of the magazine unit, the latter being shown in its foremost position by the full lines in Fig. 3 and shifted into an intermediate rearward position by the dotted lines in that figure.

Owing to the inclination of the tracks 9 and l0, the weight of the magazine unit will tend to cause the unit to grar'fitate toward its rearmost position and will require lifting the weight of the magazine unit when the latter is shifted forward. However, a pair of compression springs 30 is provided, one toward each side of the magazine unit. one end of each spring being arranged'to bear against part of the main stationary frame and the other end thereof bearing against an adjusting collar 31 which is threaded on or otherwise adjustable longitudinally on a rod 32 one end of which is guided for longitudinal Vmovement by a hole 33 formedin a portion of the main frame l and the other-end of the rod being pivotally connected at 84 to a crank arm 85 which may be formed as parts of the hubs of the arms 28 and 28a fixed on the shaft 27 and these crank arms project upwardly from said shaft, each spring encircling its respective rod and being thereby supported and prevented from buckling. The expansive ac*- tion of these springs will tend to push the magazine unit forwardly and the combined strength of these springs is preferably such that it counterbalances substantially the tendency of the magazine unit to gravitate rearwardly, the effort required to shift the magazine unit forwardly and rearwardly being thus made equal or approximately so, and the magazine unit being able to remain in different positions into which it is shifted. The adjustable collars enable the strength of these two springs to be adjusted as desired.

In order to facilitate the magazine shifting operation and to yieldingly retain the magazine unit in any one of the different operative positions 'into which it may be shifted, the under side of the track 9 at each side of the magazine unit is preferably provided with depressions or slight notches 9a which preferably correspond in number to the number of magazines `contained in the unit and in location to the operative positions of the different magazines;V and'these depressions receive the tops of the respective rollers 11 when the magazine unit is shifted to the point where the respective magazine will be set tomove into operative position when the forward end of the unit is lowered.

The flange l0b of the tracklO is preferably provided with similarly located notches 10 and each of the crank arms 17r carrying the rollers 15 is provided with a tooth or projection 10 which, when the forward end ofthe magazine unit is lowered, after the desired magazine has been brought into proper position, will engage in the notch 10c corresponding with that magazine, the depressions or notches 9a facilitating the bringing Vof the different magazines into operative position by resisting slightly, further shifting movement and thus informing the operator that one of the magazines is in such position that when lowered, the respective notches 10 will register with the teeth 10@l and such magazine will be brought into operative` position, the notches 10c and cooperating teeth l()d locking the magazine unit against displacement forwardly or rearwardly from operative position, after the forward end of the magazine unit has been lowered to bring the related magazine into operative position, maintenance of the proper working relationship between the escapements on the magazines in use and the actuating rods being thus insured. When the forward end of the magazine is inits lowered operative position, it

will be eiectively supported by the locking teeth *i and the rollers 15 which will both engage the respective tracks .as is shown in Fig. 2. The teeth 10F1 will be swung downwardly and thus released from the notches 10c when the handle 2() is swung in a direction to tip the forwardend of the magazine unit upwardly, so that the tooth or projection 1()d will then not interferey with forward or rearward shifting movement of the magazine unit.

The mode of operation of the magazine shifting means constructed as hereinbefore described is as follows. In Fig. 2, the, rearmost magazine is shown in operative position with respect to the distributor and channel entrance and the escapement actuatingreeds. 1n order to shift the magazine unit to bring' the middle magazine intov operative position, it is only necessary first to vswing the lever or handle 2O rearwardly from the position shown in Fig. 2 to that shown the full lines in Fig. 3, this operation raisingthe rollers. 15 and thereby tipping the forward ends of the magazinesupwardly or into the position shown in F ig,` 3, and simultaneously disengaging the teeth 10d from the notches 10C which they previously engaged, the lower ends of the magazines being then above and clear of the escapement actuating reeds and adjacent parts of the machine, this same op-` eration of ther lever Vor handle 20 acting through the link 24to swing the channel entrance from the operative position shown inF ig. 2 tothe inoperative position shown in Fig. 3 where the channel entrance will clear the upper ends of the magazines; to pull the handle or lever 26 forwardly thereby swinging the levers 28 and 28a andthe links 29 and 29a connected to their upper ends rearwardly until the middle depression 9a in each track 9 engages thetop of its respective roller 11, thus setting the 7middle magazine in properly shifted position; and to pull the handle or lever 20 forwardly to restore it to Vits initial position, this operation lowering the rollers 15 and, in consequence, the forward ends of the magazine so that the escapements of the middle magazine come into working relationship with the keyboard reeds fi and the teeth 10d are simultaneously swung upwardly to engage in the respective middle notches 1()c and simultaneously the link ,24 is pulled forwardly, returning the channel entrance 3 to its normal operative position between the distributor andthe upper end 0f the magazine in use.

The weight of the forward end of the magazine unit will serve to retain it in lowered position so that it rests on therollers 15 and the locking teeth 10d andthe escapementsof the magazine in use will thus be maintained in operative relation with the keyboard reeds. The foremost magazine may be brought into operative position by an operation similar to that just described, and to changev from the foremost magazine to one of the magazines in rear thereof, the op:`

eration will be the same except that the handle or lever 26 is shifted in the oppositeV plied to a magazine unit which is somewhat differently mounted on the main frame of the machine, it omitting the upper track on the magazine unit, as previously described, `and employing instead, a track 36 which forms a part of the main frame of the machine, one kof these tracks being provided vat each side of the magazine unit, these tracks being inclined rearwardly as shown, and the vframe 37 of the magazine unit is adapted to carry a roller 38 at each side thereof to ride on top of the respective tracks 36. The links .29a which shift the magazine unit forwardly or rearwardly on the tracks are similar to the links 29 previously described except that they are longer and are pivotally connected to the frame 37k ofthemagazine unit at 39, these links effecting the forward and rearward shifting movements by means operated by the handle 26 as hereinbefore described in connection with the other figures, and the forward end of the magazine unit being .lifted and lowered and held in the different operative positions when lowered, by means similar to that already described in connection with the other figures.

The mode of operation of the structure shown in this figure is similar to that already described, except that the rollers 38 supporting the upper portion of the magazine unit will travel forwardly or `rearwardly on the tracks 36v on the main frame, during the magazine shifting movements. The magazine shifting mechanism provided by the present invention is relativelyk simple and inexpensive, it consisting simply of the approximately concentric shafts which are supported on the main frame of the machine and the connections which lift and lower and shift the magazine unit, the construction being readily applicable to machines already inuse aswell as to new machines, and the location and arrangement of the operating handles which lift 4and lower and shift the magazine unit are such that they are within easy reach of the operator occupying his seat in front of the keyboard, and these handles may be easily swungA forwardly and rear-` wardly by the operator without requiring JLU movement ofthe magazine unit minimizes.

the effort required to shift the unit `forwardly and rearwardly, and the counter-balancing springs overcome any tendency of the magazine unit to slide rearwardly under its weight when inclined tracks are used, and the springs, moreover assist the forward movementof the magazine unit, the strength of the springs being preferably such that the magazine unit may be shifted either forwardly or rearwardly. with approximately the same eort applied to the shifting handle or lever.
